Lock-faucet



PATENT FFICEEQ JAMES SARGEN T, OF ROCHESTER, NEW YORK.

LOCK-FAUCET.

SPECIFICATION forming part of Letters Patent No. 286,077, dated ctober2, 1883. Application filed March 23, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES SARGENT, of Rochester, Monroe county, New York, have invented certain new and useful Improvements in Faucets; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the faucet. Fig. 2 is a longitudinal vertical section of the same. Fig. is a plan on an enlarged scale.

- Fig. 4c is a vertical section of Fig. 3 in line x :0. Fl 5 is a detail view in perspective, showing the tenon and slot connecting the key-plug with the spigot or valve. Fig. 6 is a side elevation similar to Fig. 1, but showing a modification.

My improvement relates to lock-faucets in which a flat key is used, which, when inserted, acts upon pins and arranges them in order, so that the plug can be turned to unlock the faucet, but when removed leaves the faucet in a locked condition.

In consists in the combination of a separate spigot in the faucet, a solid seat on the faucet, and a lock mounted independently on the seat, the key plug or boltof the faucet and the spigot being connected by a loose connection, which allows the spigot to fall without affecting the lock. I

It also consists in combining with the key plug or bolt a pin or stud, which projects out through a slot in the casing and rests over one of the screws that fastens the casing to the seat of the faucet, and prevents its removal when the faucet is locked.

In the drawings, A shows a faucet, having at one end a threaded stem, a, by which it is screwed into a cask or other receptacle, and at the other end a nozzle, Z), by which the liquid is discharged, as usual.

B is the spigot, made of conical form, as usual, and fitted in a conical seat of the faucet. This spigot has a port or passage, (1, which connects with the passage fof the faucet when the faucet is unlocked,- but is turned at right angles thereto when the faucet is looked, as shown in Fig. 2. Thus far the device is of ordinary construction. 7

O is a circular seat cast or formed solid on the top of the faucet.

D the cylindrical case of the lock, which has a flange or rim, resting in the seat, and secured thereto by two or more screws, h h, Fig. 3, which allows the case to be removed when necessary.

E is the solid key plug or bolt which rests and turns in the cylinder 1), being provided with a slot, t, for the reception of the flat key G, as is usual in flat-keyed locks.

is a projecting pin, attached fast to the bottom of the key plug or bolt, and project ing out horizontally through a slot, Z, made in the cylinder. This slot extends quarter of a circle, and allows the pin a quarter-sweep in looking and unlocking. \Vhen the faucet is locked, the pin 7c is thrown forward and rests directly over one of the screws 71, and when the key is removed the pin itself is locked,

and the screw beneath it cannot be removed. Therefore. the casing cannot be removed from the faucet. hen the lock is unlocked, the screw is free, and the casing and lock can be removed from the faucet to reach the interior.

in m and m m are a series of pins, one set resting in thekey-plug E, the other set resting in an extension, H, of the casing D, and provided with springs a a, which rest against them and force them out against the first set in the pin The ends of these two sets of pins come exactly in line. WVhen the key is inserted, as shown in Fig. 4, the pins will be thrown so that their contact ends coincide exactly with the circular joint between the key plug and the ease, and in that case the plug can be turned. Then the key is removed, the pins in the extension of the case shoot into the holes in the plug and lock it into place. This action is the same as in other locks of the kind;

In ordinary faucet-locks of this character the key plug or bolt and the spigot or key of the faucet are made in one solid piece. As the spigot is used it wears and gradually falls in its seat. This of course carries the pins in the plug out of line with those in the case and renders the lock inoperative, as the pins will not engage. A very small deflection of the pins will render the lock inoperative. Much difficulty occurs from this source. To obviate the difficulty, I make the spigot separate and independent from the key-bolt, as before described, and mount the latter upon the seat of the faucet. Therefore as the spigot wears down in its seat the lock is not affected, as the pins always remain exactly in line. To connect the key-bolt with the spigot so that the latter will turn with'the former, one of that the spigot can fall under wear without This feature is one of disengaging the parts.

This

the most important in my invention.

construction also enables the spigot to be easily removed and replaced by another at any time, which can be done by simply removing the lock at the top. r

8, Figs. 2 and 4, is a circrnnferential groove or cavity made in the seat 0 around the head of the key-plug, and u is one or more orifices opening from said groove to the outside of the faucet. By this means such liquid as works up around the spigot will fall into the groove, and will escape outward and will not be carried up into the lock through the joint between the key-plug and its casing, as would be the case were this provision not made.

In Fig.6 the faucet is turned so that the lock stands horizontally instead of vertically, as in Fig. 1. This is sometimes necessary in constrained positions. The groove and dis charge-orifice are quite essential in such case to prevent the flow of the leakage into the lock. The threaded nozzle I) is also necessary in such case toallow the liquid to be dison the seat, the key plug or bolt and spigot 0 being connected by a loose connection, which allows the spigot to fall without affecting the lock.

2. In a lock-faucet, the combination of the separate spigot B, the seat 0, made solid with 5 the faucet, the cylinder I), mounted on the seat and containing the lock, and the key plug or bolt E, resting within the cylinder, the keyplug being provided with a tenon which rests in a slot in the spigot and forms a loose con- 50 nection between said parts, as herein shown and described,

3. In a lock-faucet, the combination, with the cylinder or case of the lock secured to its seat by means of screws, of a pin attached to 5 5 the key plug or bolt projecting out through a slot of the case, and resting over one of the screws when the lock is looked, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed 60 my name in the presence of two subscribing witnesses.
